Comment Moderation

Hi, can I just check whether it is possible to enable comment moderation on BlogEngine. If so, how will I be notified when there are new comments due for approval, and how do i go about approving the comments? I'm currently using BlogEngine.Net 1.5.0.7.

Another thing I'll like to ask is whether it would be possible to retain comments, but remove the links to other websites in that particular comment? I've been getting quite a bit of spam on my blog.
